Sometimes, no matter how busy we are or how hard we work, when we look back on our day, it can seem like we didn’t really achieve very much. Why is this and what can we do to make more effective use of our time? Could the answer be simply tuning into our bodies’ and minds’ natural rhythms – more specifically the ultradian rhythm, the 90-minute cycles of attention and alertness that oscillate throughout the day? In this episode we’re joined by executive coach and author Dr Christian Poensgen, to talk about his latest book, Ultraproductive – The 90-Minute Method for More Focus, Better Sleep and Less Stress. He talks about the many factors within modern life that lead us to struggle to carry out our daily tasks, why concentrating on quality rather than quantity of focus, sleep, and relaxation is essential for our productivity, and shares some psychological tips that can help us all start making more effective use of our time.

For many of us, maths is simply a subject we studied at school to help us learn how to count, add one thing to another, and carry out everyday tasks such as managing our personal finances. But if we look more deeply, maths has underpinned the way that humans understand and interpret the world for thousands of years. Without our knowledge of maths, we’d have no smartphones and no internet, our buildings wouldn’t stay standing up, and we’d know very little about the wider Universe we live in. In this episode we’re joined by Prof Terrence Tao, a mathematician and author based at the University of California, Los Angeles to talk about his latest book, Six Maths Essentials – How to Model the World. He tells us how starting to think about numbers more abstractly opened up a whole new way in which we can understand the world around us, how innovations in maths have often helped us to solve real-world scientific problems that arose long after their initial discovery, and encourages us all to see how paying more…

For those of us who live in towns and cities, bogs may seem to be a rare environmental relic left over from times gone by, or perhaps something we’ve only encountered onscreen in spooky fantasy movies. The fact is that these peat-rich, often otherworldly landscapes are found in almost every corner of the globe, have had a deep influence on the development of human culture, and act as one of the planet’s unsung heroes in the fight against climate change. In this episode we’re joined by ecologist, climate scientist and author Merritt Turetsky, to talk about her latest book, Boglands – The Hidden World of Earth’s Most Extraordinary Ecosystems. She tells us how bogs form over thousands of years thanks to the gradual breaking down of plant matter, how, far from being pits of death and decay, bogs are teeming with a fascinating array of life, and explains how bogs act as one of the natural world’s greatest historical record keepers.

A late summer sunset, a peaceful, verdant forest, or a Shakespearean sonnet – these are all things that move us emotionally thanks to what we perceive as their beauty. But why is this so, why do environments, art, music, and even ideas move us so emotionally? In this episode, we’re joined by Prof Nicholas Humphrey, an evolutionary psychologist and author, to talk about his latest book, Why Is the World So Beautiful? Our Minds in Search of Nature’s Rhymes. He tells us how our sense of beauty is likely linked to our evolutionary tendency to seek out the patterns found in nature, why the appreciation of beauty seems to be unique to humans, and explains how our sense of beauty is anchored in the way that we try to understand the world we live in.

Whenever we buy a new product or use a service, we simply expect it to work as advertised, usually without giving much thought to how it came to being in the first place. However, behind the scenes, every piece of technology we use, be it a toaster, a lawnmower or even the aeroplane we travel in when we head off on our holidays, has gone through a rigorous series of tests to ensure its safety and efficacy. This often-overlooked aspect of our everyday existence is carried out by test engineers. In this episode we’re joined by tech journalist and author Alex Davies to talk about his latest book, How to Keep a Plane in the Sky – Tales from the Wild, Unseen World of Test Engineering. He tells us how engineers design the products we rely on to perform well beyond any expected limits of use, how they build in safeguards to account for almost every eventuality and the great lengths they go to to account for human unpredictability.

These days, supermarket shelves are filled with thousands of different products all vying for our attention; the options are almost endless. However, if we look back in time, we find that our early ancestors simply ate what they were able to hunt and gather and eventually farm. Thanks to the huge number of options we now have available, many of us choose to follow diet plans of various kinds, be it veganism, low-fat, low-carb, or the paleo diet, but what can we learn from evolutionary history about what we should really be eating if we want to live longer, healthier lives? In this episode we’re joined by Prof Daniel Lieberman, an author and evolutionary biologist based at Harvard University, to talk about his latest book, Fed Up – What Evolution Reveals about Food, Diet and Eating Well. He tells us why many of us find it so difficult to eliminate certain foodstuffs from our diets over the long-term, how humans evolved to store more body fat than other mammals, and why the good news is that humans are perhaps…

Though often thought of as the poor cousin to our other senses, our sense of smell has played a key role in human life since its very beginnings. It helps us to determine whether certain foods are safe to eat, protects us from environmental dangers such as fire, mould and toxic chemicals, and has even been weaponised for use as a form of racial or economic discrimination. Without it, the world would be a vastly different place. In this episode we’re joined by Dr William Tullett, an historian and author based at the University of York, to talk about his new book, Sniff – A History of Smells. He tells us how advances in technology over the last several centuries have resulted in significant impacts on the odours that pervade our everyday lives, how many of us would rather give up our sense of smell than our phones, and explains how we can all reconnect with our sense of smell to widen our experience of the world we live in.

The possibility that we may be living in a simulation created by a more technologically advanced civilisation has occupied the minds of scientists, philosophers and fiction writers for decades. We may never be able to satisfactorily answer this question, but perhaps the best way of investigating its feasibility is by looking at how we might go about creating a simulation universe ourselves. In this episode we’re joined by Prof Catherine Heymans, Astronomer Royal for Scotland, who investigates this question in her new book, How to Design a Universe – The Science of Real and Virtual Worlds, the royalties of which will be given to the Royal Observatory Trust, which supports astronomy youth projects across Scotland. She tells us what our current knowledge tells us about the way that the universe operates, explains why we’d need an enormous amount of computing power to generate a simulation universe, and investigates the question of why we, or a more advanced civilisation, might attempt to do this in the first…

Often in life, we find ourselves being accused of being lazy or accusing others of acting lazily, or maybe even becoming frustrated by what we see as laziness in our own actions. But what do we really mean by the term laziness, why is it viewed as a taboo that transcends cultures, and what effect does considering ourselves or others lazy have on our mental health? In this episode, we’re joined by Prof Katrien Devolder, an ethicist based at the University of Oxford and research leader of Project Lazy. She tells us about the different ways we view laziness in ourselves and others, why working smarter and more efficiently is often misconstrued as laziness, and the impact AI is having on our views of laziness.

No matter how gently or politely we live our lives, at one point or another, it’s inevitable that we’ll find ourselves in a situation in which we disagree with another person and find ourselves having to defend our opinion or perspective. For many of us, these situations are hugely uncomfortable, perceived as destructive, and are to be avoided at almost all costs. Why is this, could interpersonal conflicts actually be useful and even healthy in the maintaining of relationships, and what can we do to better negotiate the heated situations we sometimes find ourselves in? In this episode, we’re joined by dialogue facilitator and author Priya Parker to talk about her latest book, The Art of Fighting. She talks us through some of the common situations that are likely to trigger conflict and disagreement, explains the profound effects conflict can have on group dynamics, and tells us about the many benefits we can all gain from developing ‘healthy heat’.

When most of us think about time our minds likely turn to thoughts of the second hand that ticks around a clock, or maybe the occasions we’ve been late to catch a bus. But if we stop to think about what time actually is things quickly get more subtle and complicated. Does time only exist in our minds as a psychological illusion, does it really only run forwards and not backwards, and how close is modern physics to helping us to figure out its true nature? In this episode we’re joined by physicist, best-selling author and BBC presenter Prof Jim Al-Khalili to talk about his latest book, On Time – The Physics That Makes the Universe Tick. He tells us how thinkers going back as far as ancient Greece have struggled to define what time really is and how it works, how Einstein’s theories tell us that time can run at different rates in different circumstances, and how understanding its true nature maybe key in our search for a theory of everything.

Oftentimes in popular culture we’ll hear the term narcissist used to describe a person who has an inflated opinion of themselves, a big ego or someone who tends to overestimate their own abilities. However, in psychology, narcissistic personality disorder is defined as a diagnosable mental health condition that can cause just as many issues for those living with it as it does for those around them. In this episode we’re joined by neuroscientist and best-selling author Dr Dean Burnett, to talk about many of the misunderstandings that surround narcissistic personality disorder. He explains some of potential triggers that can lead to the development of this complex condition, why it’s innately incredibly difficult to diagnose, and how, paradoxically, many narcissists can suffer from profound feelings of self-loathing.

For a large proportion of our lives, our brains seemingly work on autopilot – the many processes the brain controls hum away behind the scenes, helping us to carry out our daily tasks. But in certain scenarios, our attention takes over, giving more conscious control of our actions. These processes, such as memory, planning and our emotional responses to the situations we find ourselves in, are known as executive functions. But how exactly do they work and is there anything we can do to train them to perform more effectively? In this episode we’re joined by the neuroscientist and author Dr Adrian Owen, to talk about his latest book, Think Before You Think – Understanding Your Brain’s Mission Control. He shares his insights into how our brains operate when we’re confronted by different situations, points out some of the pitfalls built into the way we observe and respond to the world, and explains how we can all benefit from paying more attention to why we think and act in the way we do.

It’s clear to all of us that the rapid progress that technology has made over the last century or so has had profound impacts on almost every aspect of our lives. But often, the impact on our emotional well-being associated with these great changes is overlooked, or, if mentioned at all, portrayed in a largely negative light. Why is this? Is it simply down to our innate fear of the new or our natural tendency to see the downsides that accompany change? Could it be the case that this mode of thinking is leading us to miss the many ways in which new technology can help our emotional lives to flourish? In this episode, we’re joined by Pamela Pavliscak, a researcher and author whose work focusses on the intersection of technology and our emotions, to talk about her latest book, All the Feels – How Technology Can Change our Emotional Lives for the Better. She tells us how often the arguments surrounding issues such as screentime and its impact on our emotional lives are lacking in nuance, how the sharing of memes…

It’s a good bet that if most of us were to glance around our living rooms or offices, we’d quickly spot all manner of electronic devices that are powered by microchips. Since their introduction in the 1950s, chips have become one of the fundamental building blocks of the various digital technologies we rely on in our daily lives.

It was previously thought that once our brains suffer an injury due to stroke or trauma, the potential for recovery was severely limited. But recent developments in medicine have proven that this isn’t the case; our brains are, in fact, capable of miraculous acts of healing. This is thanks to a process known as neuroplasticity, a concept that’s changing the way that medical practitioners are helping patients suffering from brain injuries regain their health. In this episode, we’re joined by neurologist and author Orlando Swayne to talk about his latest book, How to Use a Fork – Stories of Mending the Broken Brain. He tells us what happens in our brains following injury, how learning new skills can change the structure of our brains, and how we can use this process to help people recover from strokes, aneurysms and other debilitating brain injuries.

Every minute of every day, our bodies are flooded with a complex web of hormones – chemical messengers that travel through the bloodstream, coordinating everything from our blood pressure, body temperature, metabolic rate and even our emotions. When this system is functioning correctly, we barely notice its actions, but if it begins to misfire, it can lead to profound issues in everything from fluctuations in our energy levels or moods to the way our bodies develop as we age and even our appearance. In this episode, we’re joined by Dr Saira Hameed, an endocrinologist based at Imperial College London NHS Trust and best-selling author, to talk about her latest book Signal – The Inside Story of Our Hormones. She tells us how, despite being so tiny, the many hormone-producing glands situated throughout our bodies have a huge impact on our health and wellbeing, the many issues that can arise due to the overproduction or underproduction of hormones, and the new therapies in the pipeline we may be able to use to…

Becoming a parent is undoubtedly one of the biggest events that can occur in any of our lifetimes – suddenly we have a tiny living being to take care of that demands the majority of our thoughts, time and attention. Of course, this can at times feel overwhelming and often leads us to look for help and advice from our parents, grandparents or close friends. But what strategies do parents in the animal kingdom use to raise their young, and is there anything we humans can learn from them? As part of our Nature's Unsung Heroes miniseries, we’re joined by science writer Elizabeth Preston to talk about her latest book, The Creatures’ Guide to Caring – How Animal Parents Teach Us That Humans Were Born to Care. She tells us how orca grandmothers pitch in to help with the raising of their grandchildren, how in some species of monkeys the father takes on most of responsibility for taking care of their offspring, and how we can learn so much more about ourselves as humans by paying deeper attention to the wider world…

While the larger, more impressive or charismatic animal and plant species often receive the most attention, the natural world is filled with lesser-known or even misunderstood organisms without which life on planet Earth would look very different indeed. If you’d like to learn how plankton plays a vital role in regulating the health of the entire planet, how, despite being a bit icky, parasites play an essential part in helping the ecosystems they live in thrive, or why we have many fascinating lessons to learn from the different strategies animals use to raise their young, why not check out the four-part Nature’s Unsung Heroes miniseries starting Friday 5th June!

Whether it’s the swab tests many of us use to help us piece together our family trees, the painstaking detective work carried out by forensic scientists, or its use in medical screening to look for signs of our predisposition to develop certain diseases, DNA science has become a regular fixture in news stories, pop culture and dinner table conversations in many of our homes. But how exactly do these processes work, what can they really tell, or not tell us, and what developments can we expect in the future? In this episode, we’re joined by Prof Turi King, the director of the Milner Centre for Evolution at the University of Bath, co-presenter of the BBC’s DNA Family Secrets and best-selling author, to talk about her latest book, The Secrets of DNA – How Genetics has Changed the World. She tells us about the fascinating stories surrounding the development of fingerprinting techniques that now allow us to identify unique individuals based on their DNA alone, how forensic scientists really use DNA science to…

Traditionally, ecologists wanting to take stock of the diversity, health and population levels of animal species within a given environment have needed to tie on their boots, get out in the field and painstakingly record what they are able to observe manually. But the emerging field of ecoacoustics – the use of sound recording to survey the biodiversity within ecosystems – is promising to be a game-changer in the way researchers are able to approach this work. As part of our Science of Sound miniseries, we’re joined by Dr Sarab Sethi, the head of the ecosystem sensing research group at Imperial College London. To talk about his work in this exciting new field. He tells us how advances in technology are providing new methods of monitoring wildlife in greater detail than ever before and why cross-collaboration between engineers and conservationists is vital in the fight against biodiversity loss.

Our world may look vibrant and full of color. But in reality, our human eyes are only picking up the tiniest slice of all the light shining in the Universe. To astronomers this hidden light is just as important as the red greens and blues we can see. We talk to Alfredo Carpineti about what secrets are lying in the Universe beyond human vision, while celebrating another aspect that the rainbow has come to represent - the LGBT+ community.

When it comes to the sounds we encounter in the natural world, few have the beauty, elegance and variety of birdsong. But these distinctive vocalisations are not simply static calls that are common to all birds of a certain species that are passed on from one generation to the next. They vary from region to region and even evolve in single populations over time in much the same way that the style of music in the pop charts changes over time. As part of our Science of Sound miniseries, we’re joined by Dr Nilo Merino Recalde, a senior conservation scientist at the RSPB, to talk about the fascinating science behind the evolution of birdsong. He tells us about his work on tracking the evolution of birdsong as it passes from place to place and from generation to generation, how advances in AI technology are enabling birdsong researchers to learn more about this process than ever before, and what this research can tell us about the evolution of culture in the animal kingdom as a whole.

Over thousands of years, human beings evolved to walk upright on two legs, efficiently and over long distances. But these days, thanks to changes in our lifestyles, we’re becoming more sedentary than ever, and this is having profound effects on our health and well-being. In this episode, we’re joined by Courtney Conley, a doctor of chiropractic medicine, and Milica McDowell, a doctor of physical therapy and exercise physiologist, to talk about their latest book, Walk – Your Life Depends on it. They tell us why the oft-quoted 10,000 steps rule has no grounding in science, and was in fact originally, dreamt up as a marketing slogan to sell pedometers in the 1960s, explain the many things the way we walk can tell us about that state of our health, and give us some advice on what we should look out for when shopping for shoes that will help us get the most benefit from our daily walks.
